Maxillary sinus shows radiopacity; which is present despite the position in which the radiograph is taken. Usually, the radiopacity has convexity pointing upward. Malignancy: Onhgren's line. Sinus is radioopaque. Sometimes, destruction of walls of sinus is seen and is diagnostic of malignancy
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
The frontal sinuses can be asymmetric in normal individual. Usually, frontal sinus shows radiolucent shadow and individual cells are made out, giving it a scalloping or clove-like appearance. Chronic frontal sinusitis: Increased frontal sinus opacity. Normal scalloping absent. Osteoma: Marked radiopacity is seen. (Denser than bone ...
The radiopacity of a given endovascular device is important since it allows the device to be tracked during the interventional procedure. The two main factors contributing to a material's radiopacity are density and atomic number. Two common radiodense elements used in medical imagery are barium and iodine.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
This condition arises as a response to dental infections, such as periapical pulp inflammation or low-intensity trauma. The lesion typically appears as a radiopacity in the periapical area due to the sclerotic reaction. While most commonly associated with non-vital teeth, condensing osteitis can also occur in vital teeth following occlusal trauma.
The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck. It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area.
Radiopacity is one of the key considerations in the design of various devices such as guidewires or stents that are used during radiological intervention. The radiopacity of a given endovascular device is important since it allows the device to be tracked during the interventional procedure.
